An independent 2026 review of OG Kush, the indica-dominant classic that fathered a whole generation of hybrids. The debated lineage, the limonene-led fuel-citrus-pine profile, the strong yield, the fast 8-week flower, the potent happy-then-relaxing effect, and who should grow it.
Quick answer: OG Kush is the West Coast benchmark, the indica-dominant strain behind an enormous family of OG and Kush crosses. ILGM lists its OG Kush feminized at 27 percent THC with a fast roughly 8-week flower and a solid 17 ounces per square meter indoors. The reward is that unmistakable fuel-citrus-pine nose and a potent, happy, deeply relaxing effect. ILGM rates it intermediate, so it grows best for someone with a run or two of experience.
Few strains have shaped modern cannabis the way OG Kush has. ILGM calls it the backbone of West Coast hybrids, and that is not marketing: cross the catalog of famous American strains and a huge share of them have OG Kush somewhere in the family tree. The name itself became a genre. Yet the exact origin is one of the great debates in cannabis. The most widely accepted account traces OG Kush to a Chemdawg crossed with a Hindu Kush line, stabilized in the 1990s by growers working between Florida and Los Angeles. Chemdawg contributed the pungent, gassy character and the base effect, while the Hindu Kush side brought the dense, resinous indica structure.
What is not debated is the result. OG Kush is indica-dominant, listed around 75 percent indica, and it carries a potent, well-rounded effect that made it the standard other strains were measured against for years. If you are exploring the classics that anchor the ILGM catalog, our White Widow review covers another foundational hybrid growers often weigh against OG Kush.
Because OG Kush has been reproduced and reworked for decades, the seed source matters for getting a stable, true-to-type plant rather than a loose knockoff. Our full ILGM Seed Bank review covers how their catalog, shipping, and germination guarantee work, and ILGM carries OG Kush as both a feminized photoperiod line and an autoflower version.
ILGM rates OG Kush as intermediate, and that is a fair call. It is not a plant that punishes mistakes the way some finicky exotics do, but it is not the most hands-off strain either. It wants a stable environment and a grower who watches it, which is why we point true beginners toward a simpler autoflower first and treat OG Kush as a strong second or third grow.
OG Kush is a fairly tall, branchy plant, listed around 35 to 63 inches, so it needs vertical room and rewards canopy management. Topping and low-stress training open it up and turn its height into more even bud sites, which matters for pulling the strong yield it is capable of. A ScrOG net suits it well in a tent. Its buds are dense and heavy, a classic indica trait, so supporting the branches in late flower is worth planning for.
Feeding is moderate to hearty, and the thing to watch is airflow. Those dense OG buds hold moisture, and in a humid late flower they can invite mold if the canopy is packed. Good air movement and sensible defoliation keep that risk down. Ramp nutrients gradually and read the plant rather than forcing it. The base setup principles are in our Learn to Grow at Home guide.
OG Kush does best in a warm, controlled environment with moderate humidity. Soil tends to bring out the fullest fuel-citrus-pine terpene expression, while coco and hydro can push slightly faster growth. Because so much of OG Kush's value is in that aroma, many growers run it in soil to protect the terpene profile, and give it the airflow its dense structure needs.
OG Kush delivers on volume as well as quality, which is part of its staying power. ILGM lists indoor yields around 17 ounces per square meter and outdoor yields around 16 ounces per plant in good conditions. That is a genuinely strong return for a strain this potent and this flavorful, and training the canopy is the way to reach the top of that range on a tall, branchy plant.
Flowering is fast for the category. ILGM lists the feminized line at around 8 weeks, quick for a potent indica-dominant photoperiod, and the autoflower version finishes even sooner, closer to 7 weeks of flower. With a few weeks of veg the full indoor cycle lands around 12 to 14 weeks from seed to harvest. Outdoors, OG Kush prefers a warm climate with a dry finish. Northern growers, including in Michigan, get more reliable results indoors, and the frost-date and season-length guidance from Penn State Extension is a useful reference for timing any outdoor crop in a cold-fall region.
OG Kush is potent, and the effect is why it became a legend. Users consistently report a fast, happy, uplifting rush that lifts the mood and clears the head, followed by a deep, spreading body relaxation as the indica side takes over. It is strong and well-rounded rather than a pure sedative, which is why it works for a wide range of people and situations. Because it is potent, newer users should start with a small amount. We are not making medical claims; we are reporting what users commonly report, and any health-related use should be discussed with a qualified medical professional.
The aroma is the other half of OG Kush's fame, and it is instantly recognizable. ILGM lists it as citrus, earthy, pine, and woody, and the classic descriptor adds the gassy, diesel-like note that OG is known for. That fuel-over-lemon-and-pine signature comes largely from limonene, caryophyllene, and myrcene. It is one of the most distinctive profiles in cannabis, and once you have smelled a proper OG you never mistake it.
Cure makes or breaks a terpene-forward strain like this. Two weeks is a minimum, and four to six weeks of slow cure is where the fuel, citrus, and pine settle into their fullest expression. Rushing the cure throws away the exact character that makes OG Kush worth growing.
Grow OG Kush if you want a genuinely legendary, potent strain with a strong yield and the most recognizable fuel-citrus nose in cannabis. Its fast flower and solid production make it efficient, and it is the obvious pick for anyone who wants to grow a true classic rather than a novelty cross. A grower with a run or two of experience will get the most out of it.
Look elsewhere if you want the simplest possible first grow, where a beginner autoflower is a gentler start, or if you specifically want a sweet or fruity flavor rather than fuel and pine, in which case a dessert strain like Girl Scout Cookies or a grape-forward indica like Granddaddy Purple fits better. If a heavy pure-sedative nightcap is the goal, those deeper indicas lean further couch-ward than OG's more balanced effect.
OG Kush earned its place as the West Coast benchmark, and it still holds up. It runs true to the original: ILGM lists it at 27 percent THC with a citrus-earthy-pine-woody nose over that famous fuel note, a fast 8-week flower, and a strong 17 ounces per square meter indoors. The only real caveat is that ILGM rates it intermediate, so it grows best for someone who has dialed in an environment and can give its tall, dense structure the airflow and support it wants. For a grower who wants to raise a genuine legend, and one that yields as well as it smells, OG Kush is about as classic as the catalog gets.
If you grow in Michigan, the state's adult-use law allows home cultivation within set plant limits, and OG Kush's fast finish makes it a strong pick for a controlled indoor tent up north where an outdoor crop would run late. Our Michigan home grow guide summarizes the rules, and the official details are on the State of Michigan Cannabis Regulatory Agency site. Always confirm your own state and local laws before planting.
ILGM is the seed source we recommend for US growers, and OG Kush is one of the most established lines in their catalog. It comes as feminized photoperiod seeds for maximum size and potency, and as an autoflower version for a faster, simpler run. ILGM's germination guarantee typically applies and shipping to the US is discreet. Pack sizes, prices, and stock rotate, so confirm the current OG Kush details and any active deals before ordering.
OG Kush is an intermediate grow where airflow, support, and training separate a good harvest from a moldy disappointment.

OG Kush is an indica-dominant West Coast classic that ILGM calls the backbone of West Coast hybrids. Its exact origin is debated, but it is most commonly traced to a Chemdawg crossed with a Hindu Kush line, stabilized in 1990s Los Angeles and Florida. It became one of the most influential strains in cannabis, parent to a huge family of OG and Kush crosses.
OG Kush is very potent. ILGM lists its OG Kush feminized seeds at 27 percent THC and rates the strain intermediate difficulty. CBD is low. That potency is a big part of why OG Kush stayed a benchmark strain for decades, and it means newer users should start with a small amount and go slow.
ILGM lists OG Kush feminized at around 8 weeks of flowering, which is relatively fast for a potent indica-dominant photoperiod strain. The autoflower version finishes even quicker, closer to 7 weeks of flower. With a few weeks of veg, the full indoor cycle from seed to harvest runs roughly 12 to 14 weeks.
OG Kush is a solid producer. ILGM lists indoor yields around 17 ounces per square meter and outdoor yields around 16 ounces per plant in good conditions. It is a fairly tall, branchy plant, listed around 35 to 63 inches, so giving it space and training the canopy help it reach the upper end of that range.
ILGM rates OG Kush as intermediate. It is not the easiest first grow because it likes a stable, well-managed environment and its dense buds need good airflow to avoid late-flower mold. A careful grower with one or two runs behind them can handle it well. Complete beginners often start with a simpler autoflower before moving up to OG Kush.
OG Kush has the famous fuel-and-citrus signature. ILGM lists its aroma as citrus, earthy, pine, and woody, and the classic descriptor is a gassy, diesel-like nose over lemon and pine with an earthy base. That profile comes largely from limonene, caryophyllene, and myrcene. On a slow cure the fuel-citrus-pine character is unmistakable and is exactly what OG lovers chase.
ILGM sells OG Kush as feminized seeds and as an autoflower version, so you can pick a photoperiod plant for maximum size and potency or an autoflower for a faster, simpler run. ILGM's germination guarantee typically applies and US shipping is discreet. Pack sizes, prices, and stock rotate, so confirm the current OG Kush product details and any active deals on the ILGM site before ordering.
